Endorsement notice The text of ISO 10893-12:2011 has been approved by CEN as a EN ISO 10893-12:2011 without any modification. DIN EN ISO 10893-12:2011-07 EN ISO 10893-12:2011 (E) 4 1 Scope This p
29、art of ISO 10893 specifies requirements for the automated full peripheral ultrasonic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for wall thickness measurement. It specifies the testing method and corresponding calibration procedures. NOTE 1 Fu
30、ll peripheral testing does not necessarily mean that 100 % of the tube surface is scanned. NOTE 2 This test can be carried out simultaneously with full peripheral ultrasonic testing for the detection of laminar imperfections (see ISO 10893-8) using the same ultrasonic transducers for both inspection
31、 requirements. Under these circumstances, the minimum lamination size under detection determines the percentage of the tube surface for scanning, according to ISO 10893-8. This part of ISO 10893 can also be applicable to the testing of circular hollow sections. This part of ISO 10893 is applicable t
32、o the thickness measurement of tubes with a specified outside diameter equal to or greater than 25,4 mm and a minimum wall thickness of 2,6 mm, unless otherwise agreed on. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、nce tube tube or length of tube used for calibration purposes 3.2 reference sample sample (e.g. segment of tube, plate or strip) used for calibration purposes NOTE Only the term “reference tube” is used in this part of ISO 10893, also covering the term “reference sample”. 3.3 tube hollow long produc
36、t open at both ends, of any cross-sectional shape 3.4 seamless tube tube made by piercing a solid product to obtain a tube hollow, which is further processed, either hot or cold, into its final dimensions 3.5 welded tube tube made by forming a hollow profile from a flat product and welding adjacent
37、edges together, and which after welding can be further processed, either hot or cold, into its final dimensions 3.6 electric welded tube tube made by pressure welding, in a continuous or non-continuous process, in which strip is formed cold into a hollow profile and the seam weld made by heating the
38、 adjacent edges through the resistance to the passage of high- or low-frequency current, and pressing the edges together NOTE The electric current can be applied either by direct electrode contact or by induction. 3.7 manufacturer organization that manufactures products in accordance with the releva
39、nt standard(s) and declares the compliance of the delivered products with all applicable provisions of the relevant standard(s) 3.8 agreement contractual arrangement between the manufacturer and purchaser at the time of enquiry and order 4 General requirements 4.1 Unless otherwise specified by the p
40、roduct standard or agreed between purchaser and manufacturer, an ultrasonic test shall be carried out on tubes after completion of all the primary production process operations (rolling, heat treating, cold and hot working, sizing and primary straightening, etc.). 4.2 The tubes under test shall be s
41、ufficiently straight to ensure the validity of the test. The surfaces shall be free of foreign matter, which can interfere with the validity of the test. 4.3 This test shall be carried out by suitably trained operators, qualified in accordance with ISO 9712, ISO 11484, or equivalent, and supervised
42、by competent personnel nominated by the manufacturer. In the case of third-party inspection, this shall be agreed on by the purchaser and manufacturer. DIN EN ISO 10893-12:2011-07 EN ISO 10893-12:2011 (E) 6 The operating authorization issued by the employer shall be according to a written procedure.
43、 Non-destructive testing (NDT) operations shall be authorized by a level 3 NDT individual approved by the employer. NOTE The definition of levels 1, 2 and 3 can be found in appropriate International Standards, e.g. ISO 9712 and ISO 11484. 5 Test method 5.1 The tube shall be tested using the ultrason
44、ic single or multiple pulse echo technique, with piezoelectric or electromagnetic transducers. The ultrasound shall be transmitted in the direction normal to the tube surface, to determine that the tube thickness meets the specified requirements. 5.2 During testing, the tubes and the probe assembly
45、shall be moved relative to each other such that (with the exception provided in Note 2 of Clause 1) the tube surface shall be scanned over equidistant non-coincident helical paths along the entire length of the tube. Unless specified in the product standards or agreed on by the manufacturer and purc
46、haser, the minimum coverage shall be at the manufacturers discretion according to his manufacturing process, but shall be not less than 10 % of the surface area. NOTE Other scanning routes can be used by agreement between the purchaser and manufacturer. 5.3 The suggested maximum width of each transd
47、ucer, or each active aperture when using phased array transducers, should be 25 mm measured in any direction. However, manufacturers may use larger transducers provided they can demonstrate their capability for detecting the adopted reference standard; on request, this capability shall be demonstrat
48、ed. 5.4 The equipment shall be capable of classifying tubes as either acceptable or suspect by means of an automated trigger/alarm level combined with a marking and/or recording and/or sorting system. 6 Reference tube 6.1 The reference tube (or partly scanned tube) shall have the same nominal diamet
49、er and thickness, same surface finish, heat treatment and delivery condition (e.g. as-rolled, normalized, quenched and tempered) as the tubes under test, and shall have similar acoustic properties (e.g. sound velocity and attenuation coefficient). 6.2 The reference tube (or machined reference sample or machined block or hollow bar of steel) shall, at the manufacturers discretion, either a) have a known area with a predetermined thickness with an accuracy better than 0,1 mm, or b) have a machined
